Summary

Patients with esophageal cancer still face a high risk of recurrence after receiving neoadjuvant chemoradiotherapy (nCRT) combined with radical surgery, especially for those who do not achieve pathological complete response (non-pCR). Compared with the overall non-pCR population, the subgroup with lymph node positivity has a significantly worse prognosis. The CheckMate 577 study confirmed that in patients with locally advanced resectable esophageal cancer or esophageal-gastric junction cancer, adjuvant treatment with nivolumab after nCRT significantly prolonged disease-free survival compared with placebo (median DFS: 22.4 months vs 11.0 months; HR=0.69, p\<0.001).

The current research focus has expanded to the field of neoadjuvant chemoimmunotherapy, but the adjuvant treatment strategy after such therapy remains a blank slate. Given that esophageal squamous cell carcinoma (ESCC) is the predominant type of esophageal cancer in our country, it is of great clinical significance to explore adjuvant treatment strategies after neoadjuvant chemoimmunotherapy combined with radical resection.

Based on the above background, we have designed a randomized controlled trial (RCT) to evaluate the efficacy of adjuvant immunotherapy versus observation alone in patients with ESCC after neoadjuvant chemoimmunotherapy, with the hope of providing evidence-based medical evidence for this population.

Conditions

  • Esophageal Squamous Cell Carcinoma (ESCC)

Interventions

DRUG

Immune Checkpoint Inhibitors ( pembrolizumab, tislelizumab, sintilimab, camrelizumab, and toripalimab)

The immune checkpoint inhibitors used for adjuvant therapy after surgery were consistent with those used during the neoadjuvant treatment before surgery, including pembrolizumab, tislelizumab, sintilimab, camrelizumab, and toripalimab.

OTHER

Observation

Postoperative observation is conducted without the use of any anti-tumor treatment.
